CHALK HOLDER Filed Sept. 5, 1940 2 Sheets-Sheet 2 Patented June 17, 1941UNITED" STAT Esv PATENT OFFICE 1 v 11 Claims.

This invention relates to a chalk holderifor use in connection withbowling alleys. It is custornary to provide a block of chalk, usually-inthe form of a truncated cone, and mounted conveniently adjacent thealleyfor the use of the players in chalking their hands-as a preparation forplay. Ordinarily, the chalk cone is sup ported on the newel post, atwhich the return track for the bowling balls terminates- One object ofthe invention is to provide means for firmly securing the chalk in aposition'for use. I

Another object is to provide a base assembly adapted to be attached tothe base portion of the cone and provided with anchoring meansengageablewith cooperating means on the newel post or other support. 4

A further object is to provide a simple, durable and ornamental mountingfora chalk cone adapted to enhance the appearance of the struc-' ture towhich it is applied. I

And it is also an object of the invention to provide a holding structurefor a chalkcone designed to engage the cone firmly without'danger ofchipping or cracking it, and to be'readily releasable to permitreplacement of the cone.

Other objects and advantages will become apparent from the followingdetailed description taken in connection withthe accompanying drawingsin which: e

Figure l'is a perspective view showing the upper portion of a newel postwith the chalk cone mounted therein by means embodying this invention.

Figure 2 is a vertical section taken substantially at the axis of thecone, as indicated at line 2-2 on Figure 1 and on a larger scale.

Figure 3 is a top plan view taken partly in section, as indicated atline 33 on Figure 2.

Figure 4 is an elevation, partly in section, showing a chalk cone and amodified form of holding structure therefor.

Figure 5 is a transverse section taken as indicated at line 55 on Figure4.

Figure 6 is a detail section taken as indicated at line 66 on Figure 4.

While I have shown in the drawings, and shall herein describe in detailtwo forms of my invention as embodied in chalk cone holders, eachdesigned to be mounted on a newel post," it is to be understood that Ido not thereby intend to limit the invention to these specific forms-orto combination with the particular mounts disclosed, but aim to coverall modifications and alternative constructions falling within thespirit and scope of the invention as expressed in the appended claims. Iv I Figure Lillustrates a newel post I ll with a fragment of the returntrack H for bowlingballs extending therefrom, and with an ornamentalmetallic cap l2 whichis shown-asincluding an ashtray I3, and from whichthe chalk cone I4 rises'in convenient position for useflby' the players.Figure '2 shmyvs the chalk cone Min section, with a metallic mountingflange l 5' externally tapered so as to fit snugly over the cone nearits base. Against the flat base surface of the cone there is secured ametallic bottom plate l6 ;which is formed with a central boss-l1,dimensionedto fit into the usual central axial bore N3 of the'cone. Thecap I2 of the newelpost includesa peripheralflange or skirt l9 whichoverhangs the upper end of the post and con-' forms to its contour, butis not permanently attached thereto. Thus, when desired, theentire capmay be lifted off the post for adjusting or removing the chalk cone. Thecap [2" includes a' circular opening into which there is fitted'a pan orreceptacle 20, and the latter is supported by its flange or lip 2|overlapping and secured to the'marginal portion of the cap l2 around theopening. I

The'fiange l5 includes a peripheralportion 22 'which'rests upon the capI2 "and covers the flange 2| of the receptacle 20.' It also has :anannular portion 23 which fits approximately within the receptacle 20'.Depending'hangers 24 extend from the annular portion 23 downwardly pastthebottom plate It and support a,-three armed spider 25 having athreaded hub 26. .A threadedstudZ'l,isadjustably carried in the threadedhub 26 and extends upwardly into a socket Il 'in the boss "of the bottomplate IS. The stud 21, when adjusted to bear against the end wall of thesocket Il also exerts pressure downwardly which is transmitted by'theend portions 28 of the arms of the spider 25 to'the flanges 24 ofhangers 24 on which these arms are lodged,so-that the hangers act todraw the internally tapered flange l5 snugly onto the chalk cone l4;and, incidentally, the lower end portion '21 of the stud 2! is then:heldrigidly projecting from the hub 26 of the spider. With the parts thusadjusted a set screw 29 in the hub 26 is employed to maintain theadjustment,

impinging against the surface of the stud 21.

. It may beunderstood that thefiange .I5, bottom plate 16 and spider25-are applied to the chalk cone preparatory to placing it in positionon. the j cap l2. To. facilitate positioning the placement.

arms of the spider 25 the hangers 24 are formed with stop flanges 24 Theends 28 of the spider arms are entered in the intervals between thehangers 24, as shown in dotted lines in Figures 5 and 6, and thenrotated into engagement with the stops 24 where they are registered forlodgment on the flanges 24 of the hangers. Adjusting the threaded stud21 then shifts the spider arms into contact with the flanges 24 fordrawing the assembly snugly onto the chalk cone l4.

The projecting lower end of the stud 21 is passed through a centralaperture in the bottom of the receptacle 20 as the cone I4 is centeredtherein, and the assembly is then secured in position by means of aclamping spider 30 screwed onto the end portion 2'! of the stud. A setscrew 3| in the hub of the spider 30 serves to maintain this relation.As indicated in the drawing, the end of the stud 21 and the exposed endsof set screws 29 and 30 are formed with hexagonal sockets to receive asuitable tool, in the nature of a key .or wrench, for tightening thesethreaded members or releasing them, as

desired.

When the cone 14 has been thus positioned and attached to the cap I2 thelatter is fitted in position over the end of the newel post I; and whenreplacement of the cone l4 becomes necessary the cap I2 is merely liftedoff the newel post to afiord access to the fastening means justdescribed.

Figures 4, 5 and 6 illustrate a slightly modified construction in whichthe cone 4 and flange l5 are substantially similar to the correspondingparts already described. The flange |5 also includes the dependinghangers 24 which engage and support the arms of a spider 25, and theseparts are held firmly in position by means of a threaded central stud 21extending through the hub 26 of the spider and impinging against thecentral portion of the bottom plate |6, contracting the base of the conel4 exactly as in the form shown in Figures 1 to 3.

But in this case the hollow newel post 40 is surmounted by a permanentlyattached metallic finish cap or flange 4| having a central opening intowhich the hangers 24 extend while the flange l5 rests upon themarginalportionof the cap 4| surrounding this opening. The post 4|! may be ofhollow construction, and at a short distance below the cap 4| there isdisposed therein a threaded metallic fitting 42 supported upon abl0ck'43 secured centrally in the hollow post 40. The fitting 42 is inthe form of a boss having afoot flange 44 through which mounting screws45 extend into the block 43. The bore of the boss 42 is threaded toreceive the projecting lower end 21 of the stud 21 so that after theflange l5, bottom plate IB, spider 25 and stud 21 have been assembled onthe lower end of the chalk cone H, the cone may be anchored on the newelpost by merely entering the end 21 of the stud in the threaded bore ofthe boss 42 and turning the cone until the flange I5 fits snugly againstthe cap 4|. Reverse rotation of the cone will release it from thesupporting post when the ch'a lk has been used up or requires re- Iclaim as my invention:
